Demand for Oceaneering's products and services exhibits some seasonality, particularly within its energy-focused businesses. Q4 2025 results were in line with typical seasonality, although revenue and adjusted EBITDA declined compared to Q4 2024 due to specific project timings. Higher activity levels for ROVs are typically forecasted during the second and third quarters. The Energy business's demand is largely dependent on the oil and gas industry, which can be affected by various factors.
